This space has often hosted musings on the nature of scientific knowledge, on how medical science is based in methodological naturalism (MN), rather than supernaturalism. MN requires that our acquisition of knowledge about the natural world be based on natural phenomena. The reason for this should be quite obvious: the natural world is the only one that exists, for all intents and purposes, and explanations must be based on natural processes. Can you name any supernatural processes? Can you measure them? Of course not.
This bothers adherents of alternative medical practices. Since science doesn’t support their ideas, they would like to carve out exceptions to natural laws. Remember, we know quite a bit about the universe. We don’t understand exactly what matter is yet, but we can measure it and experience it without ambiguity. We know the universe has matter/energy; we understand pretty well the primary forces of electromagentism, gravity, small and weak nuclear; and there are probably a few other things whose effects we can measure even if they aren’t completely understood (dark energy, dark matter).
All of modern medicine works in ways consistent with our understanding of the universe. Even when we don’t completely understand something, it does not behave contrary to these laws. A beta blocker has never caused someone to levitate. No one has been revivified by electricity, a la Dr. Frankenstein (“That’s Frahnkensteen!“). Human bodies follow natural laws, and natural explanations are the ones that have explanatory power.
Since these natural laws explain what we see in the clinic and lab, what are the altmed gurus to do?
They have three main strategies, each of which is conveniently described by a logical fallacy. Continue Reading »
On Science-Based Medicine, we strive to apply the light of science and reason on all manner of unscientific belief systems about medicine. For the most part, but by no means exclusively, we have concentrated on so-called “complementary and alternative medicine” (CAM) because there is an active movement to infiltrate faith-based, rather than science-based, modalities into “conventional” medicine. Indeed, such efforts are well-financed, both by public and private organizations, and are alarmingly successful at insinuating postmodernist and pseudoscientific beliefs into academia to form an unholy new monster that has been termed by some as “quackademic medicine.”
However, one pseudoscientific belief system about medicine that we at SBM have perhaps not dealt with as much as we should is the belief that, contrary to the overwhelming scientific consensus built up over 25 years, the Human Immunodeficiency Virus (HIV) does not cause Acquired Immune Deficiency Syndrome (AIDS). True, working with Tara Smith, our fearless leader Steve Novella has published an excellent primer on the phenomenon, but not on this blog. This belief system, which is commonly called HIV/AIDS denial or HIV/AIDS denialism, is championed by virologist Peter Duesberg, along with a panoply of groups, such as Alive & Well AIDS Alternatives and Rethinking AIDS; blogs, such as Science Guardian, HIV/AIDS Skepticism, and AIDS Is Over; podcasts, such as How Positive Are You?; books, such as What If Everything You Thought You Knew About AIDS Was Wrong? by Christine Maggiore; and movies, such as The Other Side of AIDS (which resembles in many ways the anti-evolution movie Expelled! and the pro-quackery movie The Beautiful Truth). The influence of HIV/AIDS denialism is horrific, too, particularly in Africa, where advocates of such nonsense, such as Matthias Rath, have advocated quackery over antiretroviral therapy and had the ear of South African President Thabo Mbeki, who lost power in late 2007.
